A watermark is the simplest way to protect your photos from being used without credit. This guide covers everything you need to add professional-looking watermarks for free, directly in your browser.
Why watermark your photos?
- Copyright notice — clearly marks the image as yours even if shared without your knowledge.
- Brand visibility — every share of your photo carries your name or logo.
- Deterrence — casual scrapers and content thieves move to easier targets.
- Proof of ownership — if an image is used commercially without permission, a watermark is evidence.
Types of watermarks
- Text watermark — your name, website, or copyright notice. Fast to apply in bulk. Best for photography portfolios.
- Logo / image watermark — your brand logo placed as an overlay. More recognizable but requires a logo file.
- Tiled watermark — text or logo repeated across the entire image. Hardest to crop out. Best for high-value images.
How to add a text watermark for free
Picovert's watermark tool lets you add customizable text watermarks to multiple images at once, entirely in your browser.
- Open the watermark tool.
- Enter your watermark text (name, website URL, © symbol + year).
- Choose position: corner, center, or tiled.
- Adjust font size and opacity (30–50% opacity is usually best).
- Drop your images and click "Apply Watermark".
- Download individually or all at once.
Best practices for watermarks
- Placement — avoid the center (viewers' natural focus). Bottom-right corner is the convention for photography.
- Opacity — 30–50% makes it visible without being too intrusive. Too transparent and it's easily removed; too dark and it ruins the photo.
- Color — white or light gray works on most photos. Use a dark color on light backgrounds.
- Size — the text should be readable but not dominant. Roughly 3–5% of the image width.
Can watermarks be removed?
Yes — any watermark can be removed with enough effort. But the goal isn't perfect protection; it's raising the cost enough that casual infringement isn't worth it. A tiled watermark is significantly harder to remove than a corner stamp.
Adding watermarks in bulk
Picovert's tool supports batch watermarking — drop 20 images, set the watermark once, and apply to all. This is useful for watermarking an entire photo shoot before uploading to a portfolio or client gallery.
